New Friedrich AC and Coolant


Hello,

My wife and I recently bought a Friedrich AC and wanted to know if there was any way to replace the R-22 coolant with the more environmentally friendly R-410. As far as I can tell, this would not be possible due to R-410 running at higher pressures. Can someone confirm this?

Thank you.

Joel

the money spent you could buy 2 new 410A units converting,and nobody would touch it anyway..oil,compressor,wiring.the enviorment is only damaged when the 22 is vented not running within the system.rumor hasit there is a ozone hole over NASAs florida launch sites for the shuttle see that Liquid Ox blastin' out of that tail..nice thoght but enjoy the cooling and forget it. R-22 runs 260PSI on a hot day with the sun right on that condenser ...R410A runs up in the 800 PSI range

Yes. 1.5 to 2X higher. The R410 uses a polyester oil and R22 mineral oil so no way to mix the 2. There is a environmentally friendly synthetic R22 for future use. Just came out this year and no one knows for sure if it will really work and may be VERY expensive.

Thank you for the feedback! My wife was worried that we were harming the ozone layer just by USING the AC.

No, It has to leak out for any harm to be done.
